[0023] Specifically, the basic principle of the electric luggage case is that the interior of the case body 1 can be used to store items. When the electric luggage case needs to be ridden, the battery module supplies power to the electric telescopic rod 2 to drive the telescopic armrest 3 to extend, and the telescopic armrest 3 drives the front wheel 5 to shift. The user rides on the case body 1 and places his hands on the knob handle 4. After the telescopic armrest 3 is extended, the height can be adjusted and fixed according to the situation; The user rotates the rotating handle, and the battery module supplies power to the driving components, so that the motor drives the rear wheel group 6 to rotate under the deceleration of the reducer, thereby achieving electric movement of the suitcase.

[0024] In a specific embodiment, as shown in the attached Figure 1 , 4 As shown in Figure 5, an adjustable seat plate structure is provided at the top of the box body 1 on one side of the telescopic rod 7, and the adjustable seat plate structure includes two support plates 8, both of which are installed at the top of the box body 1 and are located on one side of the telescopic rod 7, and a flip plate 9 is rotatably provided between the two support plates 8, a rubber cushion 10 is installed on the upper surface of the flip plate 9, and a handle 11 is installed on the lower surface of the flip plate 9, screws 12 are provided at both ends of the flip plate 9, and the two screws 12 extend to one side of the corresponding support plate 8 respectively, and a locking nut 13 is installed on the external thread of the screw 12.

[0025] Specifically, the structure is used to provide a comfortable riding seat for the user, and does not affect the user's lifting of the box body 1. Specifically, when riding, the user can sit on the rubber cushion 10 on the upper surface of the flip plate 9, which provides good comfort for the user. When the box body 1 needs to be lifted, the locking nut 13 is rotated to both sides, and the flip plate 9 is rotated between the two support plates 8 so that the handle 11 is facing upward, and finally the locking nut 13 is tightened, and the user lifts the box body 1 through the handle 11; Similarly, when the user needs to sit on the box body 1, the rubber cushion 10 can be directed upward in the same manner. This structure can realize the mutual conversion of the use of the rubber cushion 10 and the handle 11, thereby improving the use effect.

[0026] In a specific embodiment, as shown in the attached Figure 1 , 6As shown in , 7 and 8, the surface of the telescopic armrest 3 is provided with two extendable footrest structures, and the extendable footrest structure includes a fixed plate 14, the fixed plate 14 is fixedly mounted on the surface of the telescopic armrest 3, a rotating rod 15 is rotatably provided on the surface of the fixed plate 14, one end of the rotating rod 15 is provided with a sleeve 16, an extension rod 17 is slidably provided inside the sleeve 16, a pedal rod 18 is fixedly provided on the surface of the extension rod 17, a distance adjusting block 19 is provided inside the sleeve 16, a movable block 20 is provided at the bottom of the distance adjusting block 19, a spring sheet 21 is fixedly provided between the distance adjusting block 19 and the movable block 20, and the extension rod 17 is provided with a footrest 18. One end of the extension rod 17 is fixedly connected to the movable block 20, and two mounting grooves 22 are provided on the inner wall of the sleeve 16, wherein a screw rod 23 is provided inside one of the mounting grooves 22, and a slide rod 24 is provided inside the other mounting groove 22, and a threaded block 25 and a slide block 26 are provided outside the screw rod 23 and the slide rod 24, respectively. An adjusting block 27 is fixedly provided on the top of the screw rod 23, the threaded block 25 is located outside the screw rod 23 and is threadedly connected to the screw rod 23, and the slide block 26 is slidably connected to the outside of the slide rod 24, and the threaded block 25 and the slide block 26 are respectively fixed on both sides of the outer wall of the distance adjustment block 19.

[0027] Specifically, the structure can provide good support and stretching effect for the user's feet. Specifically, when the user sits on the box body 1 and shifts, the user can place both feet on the corresponding footrest rod 18 to support the feet. According to the height of different people, first rotate the corresponding adjustment block 27 to rotate the screw rod 23 and drive the threaded block 25 to move up and down. The slider 26 is used to slide the distance adjustment block 19 inside the sleeve 16 under the sliding guide outside the slide rod 24. The sleeve 16 drives the movable block 20 to adjust up and down through the spring sheet 21, so that the extension rod 17 is adjusted inside the sleeve 16, and the height of the footrest rod 18 is adjusted to ensure that the feet of users of different heights are comfortably placed on the footrest rod 18. After the user's feet are on the pedal rod 18, the user can apply downward pressure to the pedal rod 18, so that the extension rod 17 drives the movable block 20 to move. Since the distance adjustment block 19 will not shift under the restriction of the threaded block 25 and the screw rod 12, the movement of the movable block 20 can stretch the spring sheet 21. After the spring sheet 21 is stretched, it can provide a reverse force to the pedal rod 18, which can play a good stretching effect on the user's feet and leg exercise. At the same time, when the user applies force on the leg, the rotating rod 15 rotates on the surface of the fixed plate 14, which can facilitate the user's legs to swing and stretch in a small scale. Moreover, in this structure, by sliding the adjustment block 27 inside the sleeve 16, not only the position of the pedal rod 18 can be adjusted, but also the tension of the spring sheet 21 can be adjusted according to the situation, thereby adjusting the strength of the user's leg stretching; In short, this structure can adjust the height of the footrest 18 according to people of different heights, making it convenient for users to place their feet on the footrest 18 for support. At the same time, it can stretch and swing the user's legs to avoid discomfort caused by the user's legs maintaining a posture during use, thereby improving the use effect. It is suitable for riding or use when there are insufficient seats in a station.

[0028] In a specific embodiment, as shown in the attached Figure 2 , 3 As shown, an auxiliary upper and lower structure is provided at the bottom of the box body 1 between the front wheel 5 and the rear wheel group 6, and the auxiliary upper and lower structure includes two electric push rods 28, and the two electric push rods 28 are fixedly installed at the bottom of the inner cavity of the box body 1. A mounting plate 29 is provided at the bottom of the box body 1, and a connecting block 30 is fixedly provided at the output end of the two electric push rods 28. Two concave seats 31 are provided on the surface of the mounting plate 29, and the connecting block 30 is rotatably connected inside the concave seat 31. A rectangular groove 32 is provided on the surface of the mounting plate 29, and a guide rod 33 is provided inside the rectangular groove 32. A guide block 34 is slidably provided outside the guide rod 33, and the guide block 34 is fixedly connected to the corresponding concave seat 31. A plurality of grooves are provided on the surface of the mounting plate 29, and auxiliary rollers 35 are rotatably installed inside the plurality of grooves.

[0029] Specifically, the structure can facilitate the operation of the box 1 to go up and down stairs, and the user does not need to lift the box 1 laboriously during the stairs. Specifically, when going up and down stairs, the user pulls out the telescopic pull rod 7, and pulls the box 1 by tilting the telescopic pull rod 7, so that the box 1 moves through the rear wheel set 6; When encountering stairs, the two electric push rods 28 extend downward and the lengths of the output ends of the two electric push rods 28 are different, ensuring that the output end of one electric push rod 28 has a long extension length and the output end of the other electric push rod 28 has a short extension length. During the extension process of the electric push rods 28, the connecting block 30 rotates inside the concave block, and the other concave block slides and guides outside the guide rod 33 through the guide block 34. At this time, the erection plate 29 is in an inclined state; The inclined mounting plate 29 is mounted between two staircases. At this time, when the box body 1 is pulled, multiple auxiliary rollers 35 on the mounting plate 29 roll inside the corresponding grooves to assist the box body 1 in going up and down the stairs. The user does not need to lift the box body 1 by the handle 11, thus saving manpower.

[0030] Working principle of the present invention: The present application provides an electric suitcase with a displaceable front wheel. In specific operation, first, the electric telescopic rod 2 is powered to drive the telescopic armrest 3 to extend, and the telescopic armrest 3 drives the front wheel 5 to move. The user sits on the rubber cushion 10 on the box body 1 and places his hand on the knob handle 4. The knob is rotated to make the driving component drive the rear wheel set 6 to rotate, thereby achieving the purpose of electric movement of the suitcase. According to the height of the user, the threaded block 25 is driven to move up and down by the rotation of the screw rod 23, so that the extension rod 17 is adjusted inside the sleeve 16, and the height of the footrest rod 18 is adjusted to ensure that the feet of users of different heights are comfortably placed on the footrest rod 18. At the same time, by applying pressure downward to the footrest rod 18, the extension rod 17 drives the movable block 20 to move and stretch the spring sheet 21. After the spring sheet 21 is stretched, it can provide a reverse force of the footrest rod 18, which can have a good effect of stretching the user's feet and exercising the legs. At the same time, when the user applies force on the legs, the rotating rod 15 rotates on the surface of the fixed plate 14, which can facilitate the user's legs to be swung and stretched on a small scale; When encountering stairs, the telescopic pull rod 7 is pulled out, and the box body 1 is pulled obliquely by the telescopic pull rod 7, so that the box body 1 is moved by the rear wheel set 6, and the two electric push rods 28 are respectively extended downward to different lengths so that the erection plate 29 is erected in an oblique state between two adjacent stairs. At this time, when the box body 1 is pulled, the multiple auxiliary rollers 35 on the erection plate 29 roll inside the corresponding grooves to assist the box body 1 in going up and down the stairs. The user does not need to lift the box body 1 by the handle 11, which saves manpower; The flip plate 9 can be flipped and fixed between the two support plates 8 to achieve mutual conversion of the use of the rubber cushion 10 and the handle 11, thereby improving the use effect and making it convenient for the user to sit on the rubber cushion 10 or lift the box body 1 by the handle 11.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
